Can anyone test 6.1.32 with Core Isolation enabled?

Post by fred1 »

I am still on 6.1.26 because that is the last version I could confirm working with Core Isolation enabled.

Last time I upgraded to test, and downgraded again, VirtualBox's network drivers got corrupted and would never install again, having me to reinstall my entire operating system to fix it.

So I rather not upgrade and downgrade VirtualBox again to test this.

Yes, I've tested it myself, but I cannot recommend it to you at the moment. VirtualBox 6.1.32 solved the HVCI issue, but VMs running with Hyper-V active (with or without HVCI) got considerably slower than under the previous VirtualBox versions for many users. And consider my "considerably" as an understatement. ;)

I am in total agreement with "And consider my "considerably" as an understatement. "

Please try the VirtualBox test build 6.1.35r150972 (or newer), which includes a potential bugfix.
